Fish plate, also known as splice bar or joint bar. It is a kind of metal plate used to connect the ends of two rails into a continuous track. It doesn't look like much, but it is an indispensable railway fastener, playing a very important role in railway transportation. The fish plate is used in conjunction with the fish bolt. It is much more labor-saving and easier to install than rail butt welding technology.There are some screw holes in the middle of the fish plate, and there are upper working surfaces in contact with the lower part of the rail head and lower working surfaces in contact with the upper part of the rail bottom along the horizontal axis of the screw hole. The fish plate is a kind of rail joint, and the structure is weak.
It is required that the fish plate must be tightly attached to the steel rail because there is a lot of impact force when the train passes through. Therefore, it is necessary to use steel with good rigidity and toughness for manufacturing the fish plates, increasing the allowable stress of railway fish plates by heat treatment, and improving the hardness and wear resistance of its supporting surface.
Types of fish plate in railway
Types
Normal fish plate
The normal fish plate is the most common type, which is widely used in various kinds of rails. It is ordinarily made of medium carbon steel and high carbon steel. And there are two types of normal fish plate, four holes normal fish plates and six holes normal fish plates.
Compromise fish plate
Compromise fish plates are used to connect two different rail tracks, which have two separate sections, one is installed on the outside of the rails, and another is installed on the inside of the rails. There are upper working and lower working surfaces in contact with the rail along the horizontal axis. And the back of the upper working surface extends upwards, forming a transition section above the rail surface, which forms a bridge arch shape along the direction of the fish plate.
Joggled fish plate
Joggled fish plate is another type of fish plate, that has the same function as the normal fish plate. The joggled fish plate is different in shape from a normal fish plate. it is a special forged fish plate that includes a fish plate and a bulge section in the middle. The joggled fish plate can effectively clamp and repair the welded steel rail, allowing the train to pass through the railway track safely. It has the characteristics of following rail deformation, a wide range of applications, convenient maintenance, durability, simple installation, and excellent fatigue resistance.
